IMAGE PROCESSING SYSTEM AND IMAGE PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18330290 titled 'IMAGE PROCESSING SYSTEM AND IMAGE PROCESSING METHOD
The patent application describes an image processing device that reduces grid pattern noise in captured images, improving image quality.
- Image input circuit receives pixel values from an image sensor.
- Kernel manager generates kernels corresponding to a grid pattern based on an array pattern of a color filter array in the image sensor.
- Preprocessor performs a blur operation based on pixel values and kernels, amplifying pattern pixel values related to the grid pattern.
- Grid pattern detector changes irrelevant pixel values to a preset value based on the kernels, generating a grid image with only the grid pattern.
Potential Applications: - Photography and videography industries for enhancing image quality. - Surveillance systems to improve image clarity for security purposes.
Problems Solved: - Reducing grid pattern noise in captured images. - Enhancing overall image quality by eliminating unwanted pixel values.
Benefits: - Improved image quality with reduced noise. - Enhanced clarity and detail in captured images.
Commercial Applications: - "Image Processing Device for Noise Reduction and Quality Improvement in Captured Images": This technology can be utilized in digital cameras, smartphones, security cameras, and other imaging devices to enhance image quality for commercial purposes.
Prior Art: No prior art information is provided in the abstract.

Original Abstract Submitted
An image processing device that reduces grid pattern noise in a captured image and which improves captured image quality may include an image input circuit configured to receive pixel values from an image sensor, a kernel manager configured to generate kernels corresponding to a grid pattern determined based on an N×N array pattern of a color filter array included in the image sensor, a preprocessor configured to perform a blur operation based on the pixel values and the kernels and to amplify pattern pixel values corresponding to the grid pattern, among the pixel values, and a grid pattern detector configured to change pixel values irrelevant to the grid pattern, among the pixel values, to a preset value based on the kernels and to generate a grid image including only the grid pattern.
